TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 619,228, dated February 7, 1899.

Application filed July 16 1898. Serial No. 686,144. (No model.)

To a/ZZ whom it may concern:

Beitknown that I, CHARLES T. RosENTHAL, of Batesville, in the county of Independence and State of Arkansas, have invented a new and Improved Temporary Binder, of which the following is a full, clear, and exact description.

The object of my invention is to provide a temporary binder that may be constructed in sections, each section being capable of independent use, and each section being furthermore so constructed that the leaves contained in a section may be removed without disturbing those of an adjoining section.

A further object of the invention is to provide a means whereby the sections may be locked closed and readily opened whennecessary.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a perspective view of a book bound by the improved temporary binder, the

Vupper cover being open and broken away.

Fig. 2 is an edge view of the book shown in Fig. 1 with both covers closed. Fig. 3 is a view of the back of a bound book, the cover for the binding device having been removed. Fig. 4 is a section taken substantially on the line 4 4 of Fig. 3, the covering for the binding device being applied. Fig. 5 is a perspective view of one end of one member of a section of atemporary binder. Fig. 6 is a perspective View of a section of the temporary binder closed, being viewed from the rear. Fig. 7 is a perspective view of the section of the temporary binder shown in Fig. 6 viewed from the front. Fig. 8 is a perspective View of a section of the temporary binder, the section being in open position. Fig. 9 is a perspective view of a lower member of a section of the temporary binder. Fig.'10 is perspective view of the locking bar or plate employed in connection with a section of the temporary binder. Fig. 11 is a perspective view of a section of the temporary binder viewed from the rear, a part of the back of the section-be ing broken away. Fig. 12 is a perspective View of a spring-guide for the locking guard or plate of a section of the binder. Fig. 13 is a transverse section taken through a section of the temporary binder, the section of the binder being closed; and Fig. 14 is a view similar to Fig. 13, the section of the binder being open and the section from the binder in Fig. 14 is taken practically on the line 14 14 of Fig. 8

A represents a section of the improved temporary binder,which section comprises a top plate a and a bottom plate ai', the two plates having a hinged connection. The top plate a is provided at its back or rear edge with a downwardly-extending ange, upon which flange knuckles 10 are produced at intervals, and the said flange at the back of the top plate a is cut away at the center to form a longitudinal opening 11. Pins 12 are secured to the top plate @,and the said pins extend downward or from the inner face of the said top plate in direction of the bottom plate a'. Between the center and each end of the top plate ct of the binder a stationary guide 14 is located. Each of the said guides 14, as shown best in Figs. l1, 18, and 14, consists of a plate riveted or otherwise secured to the under face of the top plate or member a, extending therefrom in direction of the lower plate or member a', the lower end of the guide-plate 14 be ing rearwardly curved and then carried upwardly and forwardly, preferably on a curved line, to form a hook-section 14a. The bottom plate or member a of a section of the binder is provided with an upwardly extending flange at its back or rear edge, formed with knuckles 15, adapted to enter the spaces between the knuckles 10 in the upper plate or member a, hand the hinged connection between the two members or plates is effected by passing a pin or pintle 10a through the knuckles of the two members of the'section.

The lower member or plate a of a section of the binder is provided with upwardly-extending pins 16, and these pins are adapted to pass between or alternate with the pinsl2 of the upper member a. The lower member or plate a. is provided with an opening at the central portion of its back corresponding to t the opening 11 in the the top member, (designated as 11%) and the bottom member is loo p also provided with fixed guide-plates 17, that correspond to the` guide-plates 1;4 of the upper member; but the guide-plates on the lower member a extend upwardly and are so placed as to alternate with those of the upper member. The hook-sectionsl7a of the fixed guideplates 17 extend downwardly instead of upwardly, as do the corresponding portions of the guide-plates of the upper member of asection. I desire it, however, to be understood that the hook sections of the Vfixed guideplates need not necessarily extend the length of the body of said guide-plates, as shown best in Figs. 9 and 11.

In connection with each section of the binder a locking plate or bary 18 is employed. rFhis locking plate orv bar is transversely curved, and when the two members of 'a secti'on are closed the locking plate or bar is passed between the body portions of the xed guide-plates 14 and 17 and their hook portions 14a1and 17, as is shown particularly in Figs. 8: and 11. The locking plate or bar 18 is prowith recesses 2O in its lower edge, the recesses in the upperV edge corresponding tothe number of fixed" guide-plates on the upper member of the binder-section, and the recessesin the bottom-of thesaid locking plate or bar are solocated thatwhen thesaid'locking plate or bar is drawn outward to aY certain extent the said recesses-will' beopposi'te the hookv portions of the said guide-plates and will permit the upper member of the binder-sectionl to be opened or carried' atan angle to the lower member, as shown in Fig. 8. When, however, the solid portions of the locking plate or bar are carried between the hook and body portions of thefixed guide-plates, the members of the section of the binder will be locked ina closed position and cannot be opened, as shown in Fig. 11. This latter position of the locking plate or bar is maintainedl by means of a spring-controlled guide B. (Shown applied in Figs. 3, 6, 8, and 11 and in detail in Fig. 12'.) This spring-guide B consists. of a knuckle23, through which the pintlc-l0?L of the hinge, for the members of the section passes, and' oppositely-extending ears 24,. nearl theL ends. ofthe said knuckle, which ears are adapted tof engage with the inner faces of the back flanges of themembers of the binder-section, and between the ears 24 a two-partprojeetion 251 is formed upon the knuckle 23, whieh-double-leaved projection is adapted tov entera slot 21 in the locking bar or plate 18 and then-.have its leaves turned inV opposite directions, as shown in Fig. 8. A spring 26'is coiled around the pintle, on which the guide B is mounted, and the spring serves to hold the guide in a position that will compel thelocking plate or bar to lock the membersof the binder-section closed. Vhen it is desired to open the binder-section for the purpose of introducing leaves or of removing leaves: therefrom, the locking-plate is drawn outward, as shown in dotted lines in Fig. 7

and, in positive lines in Fig. 8, thus placing the spring 2 6 of the section under tension.

A lug 28 is located at one end of either the upper or the lower member of the binder-section, the said lug being so placed as to form a guide or gage for inserting loose leaves. In Figs. 1, 2, 3, and 4 I have illustrated a number of sections combined together, and the backs of the sections are covered by a suitable strip 29.

When the sections are combined, the fixed guide-plates 14 for the upper members of the sections are secured to the under face vof the bottom member of the next section above. When a cover 30 is to be employed, the upper member of the upper section and the lower memberof the lower section are provided with knuckles 31, between which knuckles 32 are placed, said knuckles 32 being secured to the cover, a pi-ntle passing through the alinin g knuckles. The leaves are'provided with apertures 33, through which vthe pins of the members of a binder-section g are passed. vided with recesses 119- in its upper edge and I-Iaving thus described my invention, I

claim as new and desire to secure by Letters` Patent- 1.
